COUNTER-FORMING MACHINE.

Specification of Letters Patent.

Patented Nov. 24,1914.

Application led December 22. 1911. Serial No, 667,283.

T all 'whom it may concern er Bc it known that I, rlrnnnirr F.l JONES, a subject of Great Britain, residing at Salem, in the` county of Essex `and State of Massachusetts, have invented an Improvement in' Col'lnter-liorming Machines, of` which the following 1s a specilication.

This invention relates to counter-forming i machines, and is intended as an improvement upon the machine of my application for Letters Patent.;l:/:L198,a11, filed May `26, 1909, and more particularly `of any applica tion #623,918, filed April 28, 19.11;` In the machine of both applications a feeding-,andj bending device is employed to benda counter-blank into heel-form, and feed it to a mold, and means are provided for moving said device toward and from the mold. It sometimes happens that thel blank is twisted, or otherwise deformed, sothat it will not be correctly engaged ,by ithejaws of the feeding-.andbendingldevice, or it is moved while held by said-jaws, orfa counter has not been properly removedffrom the mold after being molded, and in either case it will not be `correctly delivered or fed to the mold, and inrcase said device is moved positively' as it will be by actuating-means heretoforedevised.` byi me, the `blank will obstruct its movement., and result in the destruction ofthe blank and the liability of breaking the machine. i 1 i j i @ne of the objects of my present invention is to improve the meansfor moving the feeding-and-bending device toward and from the mold, said improved means being of a yielding character, so that, .in case` movement ofsaidjdevice toward the mold is obstructed by a deformed or incorrectly disposed blank, therewill be no liability of breaking the machine."` i .l

Another object of my present invention is to provide automatic means to stop the machine in case the feeding-and-bending device should not malte its complete stroke in a direction toward the mold, which it would not do if obstructed. f

`.ln the machine of my said `application #623,948, the mold is `arrangedi in vertical positiongand the counter-blank moved toward itin a horizontal direction, and it is dillicu'lt to accurately adjust the feeding-` and-bending device with respect to the mold so that the blank will bel delivered with its i heel end close to the heel. end of the former on which the'blank is molded; and` another objectof this invention isto give tothe j machine.

feeding-and-bending device an additional.

movement in a `vertical direction toward the` former when it has reached the end of its stroke in a direction toward the mold, thus` to `bringthe blank into engaging position with the heel end of the former before the compressing-mcchanism `is operated. In the` machine ot,` the aforesaid application, the

moans to operate the side blank-engaging nippers or jaws is arranged partly on the main portion of the machine, and partly on thehead or frameof the feeding-and-bending device, but such construction willwnot admit of the aforesaid vertical movement of said device, and herein the entire operating-means for said nippers or jaws is arranged on the head, thus to admit of vertical `movement thereof.

Figure 1 is a front elevation of a feedingandbending device and means embodying my present invention for moving it toward and from the mold. Fig. 2 is a `plan View of the means to move theA feeding-andbend ving device, the `parts being in the position they will occupy when the blank is brought into the plane of the mold. Fig. 3 is a similar plan view of the feeding-and-bending device and means to move it, the parts being in the position they will occupy when receiving a blank. Fig. Ll is a detail plan view of the automatic stop-motion for the to lift the feeding-and-bending device` at the end of its stroke in a direction toward the mold. Fig. 6 is an enlarged side elevation of a portion of the head, and means to operate the side blank-engaging nippers or jaws. Fig. 7 is aplan view of the part shown in Fig. 6. F ig'. 8 is a sectional detail of the cam for operating the means to operate the side blank-engaging nippers or jaws. Fig. 9 is a verticalsectional detail of one of the side blank-engaging nippersl or jaws arranged on the head.

The feeding-and-bending device `here shown is substantially the same asishown in my aforesaid application #623,948, and is designed to take a counter-blank from a blank-adjuste' and bend it into heel-form anddeliver it to a mold, and comprises es-` sentially a head 215, which is made as a yoke, andarranged at the top of a vertical` spindle 216, having its bearing at the end ofi a longitudinally adjustable arm 217, mounted on an upright post or bar 152 to` swing` in a horizontal plane, the extent `of.

Fig. is a detail of the means far enough to receive the blank from one group of mechanism and to convey it to the mold. Said arm 217 is here made as a bracket, see Fig. l, to afford a long bearing on the post 152, and it has secured to its lower end a short arm 218, with or without a roll thereon, which engages a cam 222, secured to the rotating shaft 155, said cam acting to move the bracket 217 in a direction to vmove the head 215 'away from the mold, and to permit movement thereof in the opposite direction, and also to control such return movement. A spring 219 is arranged on a post on the bracket 217, the lower end of which engages the bracket or an arm thereon, and the'upper end of plete its stroke when moved in a direction which is connected to an arm extended from a sleeve 220, having its bearing in a bosson the side of the upper portion of the bracket, and said sleeve has secured to its upper end a horizontally arranged quadrant 221, to whichone end of a cord 223 is attached, the other end of said cord being attached to astationary post, which may be a part of the frame of the machine. As the bracket is swung outward, in a direction away from the mold, by the cam 222, and the quadrant and spring thereby moved bodily with it a pulling force upon the cord results, which acts to turn the quadrant and thereby to wind the spring, and as soon asl said cam 222 permits of return movement of the bracket, such return movement will be caused by the spring unwinding, but will be controlled by the arm 218, or roll thereon, continuously engaging said cam 222. Thus movement of the bracket and head carried by `it in a direction toward the mold is spring actuated, yet is controlled by the cam, and in case such movement is obstructed it will cause no greater pressure upon the obstruction than the force exerted by the spring, and liability of breaking the machine is avoided.

Each time the bracket 217 completes its stroke in a direction toward the mold it operates means to disconnect the elements of Y a stop-motion mechanism, so that the stopmotion will not be operated to stop the machine, but in case the bracket does not comtoward the mold, as for instance, if said movement should be obstructed, then said stop-motion mechanism will not be disconnected, and will be operated to automatically stop the machine.

Referring particularly to Fig. 4, 500 represents a cam secured to the rotating shaft 155, which is designed to make one revolution during each complete operation of the machine, and 501 is a lever engaging said cam having its hub 502,mounted loosely on the upright post 152, and 503 is a lever extended from said hub bearing a pin 504. A spring 505 is connected at one end to said lemechanism of any suitable construction, and

movement of said lever 509 in the direction of the arrow, Fig. 4, acts to operate the clutch to stop the machine, while movement in the opposite direction acts to operate the clutch yto start the machine. For the purpose'of operatingsaid clutch lever 509 by hand, a hand-lever 510 is here shown as connected to said pivot-shaft 508, by which to turn it. The bar 506 extends in a direction toward and terminates near the extremity of the lever 503, and its end is formed with a shoulder 512, which is adapted to be engaged by the pin 504 on the lever 503, so that when said lever is moved by the cam said bar will be moved longitudinally, and the short arm 507 moved to turn `the pivot-shaft and thereby move the clutch-lever 509 in the direction of the arrow. Said bar 506, however, is movable on its pivot so-that its shouldered end is movable 'into and out of position to be engaged' by the pin 504,and when moved out of positionto be engaged byl said pin, movement of the lever 503 will not operate to move the clutch-lever 509. The position of said bar 506 relative to the lever 503 is controlled by vthe bracket 217,'A and, asl here shown, said bar 506 is slotted, as at 513, to receive a pin 514 borne by an arm 515, secured to the upper end of a shaft 517, having itsl bearings in ears secured to the post, and an arm 518 is secured to the lower end of-,said shaft 517 having a pin 519 extended downwardly froml it, which is arranged to be engaged vby the bracket 217 when said bracket arrives at the end ofits stroke in a direction toward the mold. When the pin is struck by the bracket said arm 518 is moved and its shaft 517 turned, and the arm 515 swung in a horizontal plane thereby to move the bar 506 on its pivot, out of position to be engaged by the lever 503. As the bracket is moved in the opposite direction said shaft 517 and parts connected therewith are returned to normal by means of a spring 520, which is arranged upon it, and is connected at one end with it and at the other end with a fixed support. In fact, this spring acts not only to hold the shaft in normal position but also the bar 506 in position to be engaged by the lever 503. InA case the bracket meets with an obstruction on'its way to the mold, it will be apparent that the pin 519 will not be engaged, hencev the bar 506 will not be moved and will remain in position to be engaged by the lever 503, so that the clutchlever will be operated. The automatic stopmotion here shown is intended to illustrate allem only one nof the many forms which maybe employed as comingwithin the scope` of my invention.; .d ,i d u I Referring to Figs. 1 and 5, a leveras `plv- `otally Fsupported on thebracketv217 at 530,

one end off which, as 531, extendsfbeneath the lower end of the spindle216 of the oscillat-` into'engaging position withthe heel end of a vertically disposed mold-former 426. The cam-lever 533 is arranged ,to be operated` by a cam 534, secured to the rotating shaftj155, once., duringeach operationof the machine and is timedto operate the cam-lever at the moment the'head has carried the `blankinto the mold, or into the plane ofthe ,molda former thereof.` The cam-lever is pivoted` at 535.,` and is counterbalancedbya weight 536.` d In order that `the feeding-and-bending device may be raisedwhen it` has arrived `at the endof its stroke in a direction toward the mold, and not release theblank heldA by it, it has been reconstructed insome particulars, as compared with the device of the machine of the aforesaid application, as will now be described.` 4, d i

In the` present construction the means to` oscillate the head to feed the blank from a blank-adjuster to the mold is arranged entirely above the bracket ,217,` and referring `to Figs. l `to 3, an arm 225 is `arranged at right angles with respect to` an arm 550, extended from the base of the yoke or head 215, and said arm 225 bears at its extremity a `pin`k226, `with or withouta roll thereon,`

which enters a groove or way formedin the upper side` of an angularly `formed plate 227, which `is rigidly secured to an arm 55,1 fixed to the post 152.at a point above the bracket 217. As the bracket swings and the head is caused to travel in the are of a circle the pin `226 will follow in the groove in the plate 227, and as a result the head will` be oscillated, `moving from the position shown in Fig.` 2to the position shownin Fig, 3, `Said groove or `way is of sufficient depth to permit the pin 226, or roll thereon, to remain in engagement `with it, when the head is raised by the lever 531. d

In the machine of the aforesaid applica-` tions, the head has three pairs of blank-engaging nippers, one pair to engage themid# dle of the blank as 230, 231, and two pairs` to engage the sides thereof as 250, 251, but

the present invention has to do` only with the two side blank-engaging nippers, both of which are `represented in Fig.` 2and one only of which is represented in Fig. 9. These side nippers are movable `on horizontalA axesl and also are movable bodily in the are of ia `circle thereby to bend the ends of theblanlc upward and inward while it is` held by them, andsaid movements are given to said side nippers during the travel of the head., `The nipper-frames 254, arey pivoted onhorizontal pivot-studs 285, loosely1 connected tothe extremities of a pair of oppo-` sitely `extended arms 286, respectively se-d cured to apair of short horizontal `shafts 287, having `their bearings in the head,and

said shafts have secured to them` pinions Y 288, arranged a short distance apart, andz both pinions are engaged by a double rack-` bar 289, which is arranged vertically be` tween them, so that downward movement of said rack-bar acts to revolve said pinions in` opposite ways,and thereby to move the arms in opposite ways and lift the nipper frames in the arc of a circle. Said nipperframes have secured to them guiding-plates 290, which engage one or the other side of a recessed guideway 291, on the head, and, as the nipper-frames are pivotally connected with the arms 286, it will be seen that as the arms are moved and `the nipper-frames liftedby them, said nipper-frames will be turned on their pivots in `opposite ways, hence the nipper-frames are turnedwhile being lifted, the `combined movements `acting to bend the ends of the blank upward and inward `and cause it to assume -a heelform. `To move the rack-bar vertically fim-, provedzmeans are here provided which are self-contained onor in connection with the head, sothat as the head is raisedby the lever 531, saidraclcbar will be raised with it, whereas in the construction of the machine of the aforesaidapplication such lifting movement of the head is with respect to therack-bar, and in such case the pinions will beturned by the rack-bar as they are moved bodily with respect thereto by an upward movement `of the head. As here shown, the rack-bar 289 is connected at its lower end by a swivel connection, with a lever 560, secured to a pivot-shaft 561, and a .bell-crank lever is secured to said pivotshaft, one arm of which, as 563is connected by an adjustable link 564, with a lever 565, secured to the upper end of a vertical shaft 566, to the lower end of which shaft a Ilever 567, is secured having at its extremity a pin 568,` with or without a roll thereon, which` loo in turn move the bell-crank lever and turn the shaftr 561, and lift the lever 560 and thereby move the rack-bar to rotate the pinions. The other arm 570 of the bell-crank lever' has attached to it aweight 571, which acts to assist the cam 569 in performing its functions, although said weight alone is not sucient to move the rack-bar and rotate the pinions. .lNhen the head is moved lin a direction away from the mold, into the position shown in `Figs. 3 and 7, the cam-lever 567 will engage a stationary bar 580, which acts to thrust said lever in a direction toward the cam, thereby to restore the parts. Said bar 580 may be secured to the bar 551, or lto some other suitable support. As the head is raised by the lever 531, the cam-lever 567l will slide vertically lon the face of the cam 569, and the relative position of the parts will not be changed during such move ment, so that the blank-engaging nippers will not be operated by rotary movements of the pinions during such lifting movement of the head.
